It's not a fake photo. The lighthouse keeper went out when he heard the helicopter with the photographer in it, thinking that it was the rescue helicopter that he'd called for. When he realized it was the wrong helicopter, he went back inside. Just then a big wave came that would have washed him away! The story is online in several places; here is one: http://en.wikipedia.org/wiki/La_Jument

I have a large copy of this photo hanging on the wall in my home. It's one of my favorites.
